Axle is a mechanical part of a vehicle which is a device like 2 wheel seperated by a rod or other stabilizing device. Need of AxleVehicle is incomplete without axle Axle wear the whole weight of vehicle Braking & acceleration is done through axle

TypeThere are 2 type of axle 1-Dead Axle 2-Drive Axle

Dead Axle A dead axle is what that is not connected to engine. It does not turn under its own power or torque. It move only when vehicle is move due to drive axle Application & Function of Dead Axle1. It exist for load bearing purpose 2. It distribute weight of vehicle 3. Heavy transport vehicle contain multiple axle 4. Mostly dead axle contain high load bearing spring.

Drive Axle A drive axle is what that is connected to engine. Its working is that it move or turn the vehicle. Its formation is in such type that, it is split into 2 halves

Classification of Drive Axle 1. On the no of wheel drive  2 wheel drive – one drive axle  4 wheel drive – two drive axle 2. On the position of wheel drive  Front wheel drive  Rear wheel drive

Construction

The basic part of an drive axle is -

1. 2. 3. 4. 5.

Hub CV ts (Outer) Drive Shaft CV ts (Inner) Diffrential / Transaxle

1- HUB – It is locate at the end of the axle. It is used for wheel to axle.

HUB

Construction

2. CV ts- CV t is a drive line component whose output speed is equal to input speed at any angle. Eg- Rzeppa ts. Inner CV t Allow for suspension changes while axle is rotating.

Outer CV t Allow wheel to move or revolve while axle is rotating or vehicle is turning at an angle.

Construction

3. Drive Shaft/Axle Shaft – It transmit power from inner cv t to outer cv t. 4. Differential / Transaxle – DifferentialIt is a device which transfer power from drive shaft to wheel Function1. Split amount of torque going to each level. 2. Allow the wheel to rotate at diff. speed in turns. TransaxleTransaxle is a component that combines the function of transmittion,differential,drive axle into one integratedAssembly. They are fitted in 2 ways – Front to rear & Transverse They are of automatic & manual both.

Difference b/w

Front wheel drive & Rear wheel drive

Transaxle is used in FWD. Difference in length of drive shaft is more.  FWD vehicle do not turn very fast.  Torque absorb damper is used (Torsional damper)  

Differential is used in RWD. Difference in length of drive shaft is less. RWD vehicle turn very fast. Torque absorb damper does not used.

Torsional damper It is a device which is used to absorb excess torque in shaft.

Working of Torsional damper When differential send power to the wheel, the longer shaft will have less resistance because the CV t operate at less angle most of power will send to shorter shaft. Torsional damper absorb the excess torque in shorter shaft .

Working

we can understood the working in the way thatWhen the power is given by power shaft to pinion gear to ring gear gear of differential then it transmit the power individually to sun gear of each halves shaft or drive shaft then this power is transmitted through CV t & to hub then wheel. By the use of this power or torque wheel start rotating & vehicle is moving.
